FIG. 1 is a diagram illustrating an example operation of a wearable device according to various embodiments.

According to FIG. 1 , a wearable device 100 according to various embodiments of the disclosure may control an electronic device located in an indoor space (referred to as an external device hereinafter). The wearable device 100 may include a plurality of sensors, and the wearable device 100 according to various embodiments may be implemented as AR glasses, a smart watch, etc., but is not limited thereto.

For example, even if an instruction for controlling the external devices 10, 20, 30 is not separately input from the user, the wearable device 100 according to various embodiments may automatically control the external devices based on sensing data acquired through a plurality of sensors provided on the device 100.

Hereinafter, various embodiments wherein external devices can be controlled according to control information identified based on sensing data acquired through the plurality of sensors without a user's intervention will be described in greater detail.

According to an embodiment, in case the user performs an activity requiring concentration, the processor 150 may identify that the control mode is ‘a concentration mode,’ and control the external device based on the identified control mode. For example, the processor 150 may increase the illumination of the lighting device, decrease the volume of the acoustic device, and control the mobile device not to provide a notification in the concentration mode.

According to an embodiment, the processor 150 may identify an independent control mode for each of the at least one external device.

In addition, if a user instruction for controlling the at least one external device is input through the UI, the processor 150 may transmit a control signal for controlling the at least one external device to the external device through the communication interface 140.

The UI may include at least one of type information of the at least one external device, control time information for the at least one external device, or request information on the control authority for the at least one external device.

The information on the control mode for the viewing environment of the AR content may be acquired by inputting the user's biometric information and the surrounding environment information into a first neural network model, and the first neural network model may be a model that has been trained to receive input of the user's biometric information and the surrounding environment information and output control recommendation information for each of a plurality of environmental elements.

The plurality of environmental elements may include at least one of ‘the temperature,’ ‘the humidity,’ ‘the noise level,’ ‘the illumination,’ or ‘the concentration of harmful substances.’ The processor 150 according to various embodiments may acquire information on control modes for controlling each of the at least one external device of different types based on control recommendation information for each of the plurality of environmental elements. The control recommendation information according to various embodiments may include information corresponding to ‘decrease of the temperature,’ ‘decrease of the humidity,’‘decrease of the noise level,’ ‘increase of the illumination,’ or ‘decrease of the concentration of harmful substances,’ but the disclosure is not limited thereto.

The processor 150 provided on the wearable device 100 according to various embodiments of the disclosure may identity at least one external device related to a viewing environment of an AR content based on the location information of each of the plurality of external devices and the location information of the wearable device 100, and change the environment of the indoor space by controlling the identified external device. In particular, the processor 150 may identify the at least one external device related to the viewing environment of the AR content by a UWB method.

Referring to FIG. 8A, the wearable device 100 may identify that the user is reading a book around the desk 811, and acquire control recommendation information corresponding to ‘increase of the illumination’ based on the user's biometric information and the surrounding environment information. Further, the wearable device 100 may acquire information regarding ‘the concentration mode’ of the lighting devices L1, L2, L3, and control the lighting devices L1, L2, L3 such that the illumination of the indoor space is increased based on the acquired information.

The wearable device 100 may acquire only control information for the lighting device L1 around the desk 811, and transmit the acquired control information to the identified lighting device L1.

Referring to FIG. 8B, the wearable device 100 may identify that the user is sleeping around the bed 822. The viewing environment of the AR content corresponding to the case wherein the user is sleeping may be an environment wherein provision of the AR content has stopped, and in this case, the wearable device 100 may control at least one lighting device located in the indoor space in ‘the power saving mode.’

The wearable device 100 according to various embodiments may identify that the lighting device L1 around the desk 821 and the lighting device L2 around the bed 822 are external devices related to the viewing environment of the AR content, and identify that the lighting device L3 around the living room 823 is not related to the viewing environment of the AR content.
